Aquatic, wetland, and upland areas in and along the Delaware estuary provide a rich variety of habitats, home to many fish, plants, and animals. To read more about what wildlife can be found along the Tidal Delaware Water Trail, check out the Pennsylvania Wildlife Action Plan.

Red Belly Turtles (listed species in PA)

The red belly turtle has a brown to black shell with reddish bars on some scutes. This aquatic species is primarily found in large water bodies including lakes, ponds, marshes, slow-moving rivers and creeks. Redbelly turtles prefer deeper water with sandy or muddy substrate and require aquatic vegetation.

White Perch

The white perch prefer brackish waters but can also be found in freshwater. These fish begin spawning in the spring as water temperatures rise and adults move upstream to fresh water. These fish are commonly between 7-10 inches but can be as large as 22 inches.

Green Frogs

In June 2011, a large, breeding population of green treefrogs was discovered in freshwater tidal marsh in southwestern New Jersey along the Delaware River. This was the first recorded occurrence of green treefrogs in New Jersey and represents a possible range expansion past their northern-most limit in Delaware.

Freshwater Mussel

Freshwater mussels provide valuable natural benefits to our rivers such as keeping soils in place, providing food and habitat for other animals and cleaning the water in which they live. Freshwater mussels are "filter feeders," which means they trap solids in the water such as dirt, algae and other pollutants then release the clean filtered water back into the environment. The Partnership for the Delaware Estuary found one mussel bed in Southeast PA that removed 26 metric tons of solids from the water in a single summer season - as much as five grown elephants!

Over a dozen species were historically found in streams throughout the Delaware Estuary. Unfortunately, very few species are found in Pennsylvania, New Jersey, and Delaware today due to a combination of polluted water, toxic spills, over-harvesting for bait, loss of forests along streams, and loss of fish hosts needed for reproduction and dams that block fish passage. The Partnership for the Delaware Estuary is doing important work in protecting and developing the remaining freshwater mussel beds.
